Power supply for electromechanical actuator, has inverters comprising additional arms connected by bridge, where bridge is connected to each additional arm in point located between switches of additional arms

摘要

The power supply has inverters (A, B) connected to grounds (50, 51) and comprising electrical voltage sources (U1, U2), respectively. Arms (A1-A3) and arms (B1-B3) are extended at terminals of the sources (U1, U2), respectively. Each arm has upstream and downstream controlled switches (5, 6) e.g. MOSFET, placed in series, and a connection point is placed between the switches. The inverters have additional arms (A4, B4) connected by a bridge (7). The bridge is connected to each additional arm in a point located between upstream and downstream controlled switches (5, 6) of the additional arms. An independent claim is also included for a method for using a power supply.
